Android onTouchEvent() continuous touch causes system_server GC

I have a game that requires continuous touch to track user movement and draws in SurfaceView. I've noticed that at about 30sec intervals system_server will kick in with a GC and cause the game to stutter. If I don't touch the screen at all system_server will be not GC. I'm wondering if anyone else has encountered this problem before. I'm using Canvas to draw around 30+ objects on screen at once and it runs pretty smoothly (56fps) until system_server steps in... Is this something inherit to SurfaceView? It looks like 3开发者_如何学PythonD games (using GLSurfaceView) don't have this problem.

I'm developing on a Samsung Vibrant.

Thanks!

Do you allocate objects before you start the game? If you construct new objects and free old ones during the game, inevitably the GC will kick in.
